Change navbar color in Twitter Bootstrap
我将如何去修改CSS来改变Twitter Bootstrap中导航栏的颜色？
tl;dr - TWBSColor - Generate your own Bootstrap navbar
Version notes: - Online tool: Bootstrap 3.3.2+ / 4.0.0+ - This answer: Bootstrap 3.0.x
Available navbars
You've got two basic navbars:
<!-- A light one -->
<nav class="navbar navbar-default" role="navigation"></nav>
<!-- A dark one -->
<nav class="navbar navbar-inverse" role="navigation"></nav>
Default color usage
Here are the main colors and their usage:
#F8F8F8 : navbar background #E7E7E7 : navbar border #777 : default color #333 : hover color ( #5E5E5E for .nav-brand ) #555 : active color #D5D5D5 : active background Default style
If you want to put some custom style, here's the CSS you need to change:
/* navbar */
.navbar-default {
background-color: #F8F8F8;
border-color: #E7E7E7;
}
/* Title */
.navbar-default .navbar-brand {
color: #777;
}
.navbar-default .navbar-brand:hover,
.navbar-default .navbar-brand:focus {
color: #5E5E5E;
}
/* Link */
.navbar-default .navbar-nav > li > a {
color: #777;
}
.navbar-default .navbar-nav > li > a:hover,
.navbar-default .navbar-nav > li > a:focus {
color: #333;
}
.navbar-default .navbar-nav > .active > a,
.navbar-default .navbar-nav > .active > a:hover,
.navbar-default .navbar-nav > .active > a:focus {
color: #555;
background-color: #E7E7E7;
}
.navbar-default .navbar-nav > .open > a,
.navbar-default .navbar-nav > .open > a:hover,
.navbar-default .navbar-nav > .open > a:focus {
color: #555;
background-color: #D5D5D5;
}
/* Caret */
.navbar-default .navbar-nav > .dropdown > a .caret {
border-top-color: #777;
border-bottom-color: #777;
}
.navbar-default .navbar-nav > .dropdown > a:hover .caret,
.navbar-default .navbar-nav > .dropdown > a:focus .caret {
border-top-color: #333;
border-bottom-color: #333;
}
.navbar-default .navbar-nav > .open > a .caret,
.navbar-default .navbar-nav > .open > a:hover .caret,
.navbar-default .navbar-nav > .open > a:focus .caret {
border-top-color: #555;
border-bottom-color: #555;
}
/* Mobile version */
.navbar-default .navbar-toggle {
border-color: #DDD;
}
.navbar-default .navbar-toggle:hover,
.navbar-default .navbar-toggle:focus {
background-color: #DDD;
}
.navbar-default .navbar-toggle .icon-bar {
background-color: #CCC;
}
@media (max-width: 767px) {
.navbar-default .navbar-nav .open .dropdown-menu > li > a {
color: #777;
}
.navbar-default .navbar-nav .open .dropdown-menu > li > a:hover,
.navbar-default .navbar-nav .open .dropdown-menu > li > a:focus {
color: #333;
}
}
Custom colored navbar examples
Here are four examples of a custom colored navbar:

And the SCSS code:
$bgDefault : #e74c3c;
$bgHighlight : #c0392b;
$colDefault : #ecf0f1;
$colHighlight: #ffbbbc;
.navbar-default {
background-color: $bgDefault;
border-color: $bgHighlight;
.navbar-brand {
color: $colDefault;
&:hover, &:focus {
color: $colHighlight; }}
.navbar-text {
color: $colDefault; }
.navbar-nav {
> li {
> a {
color: $colDefault;
&:hover, &:focus {
color: $colHighlight; }}}
> .active {
> a, > a:hover, > a:focus {
color: $colHighlight;
background-color: $bgHighlight; }}
> .open {
> a, > a:hover, > a:focus {
color: $colHighlight;
background-color: $bgHighlight; }}}
.navbar-toggle {
border-color: $bgHighlight;
&:hover, &:focus {
background-color: $bgHighlight; }
.icon-bar {
background-color: $colDefault; }}
.navbar-collapse,
.navbar-form {
border-color: $colDefault; }
.navbar-link {
color: $colDefault;
&:hover {
color: $colHighlight; }}}
@media (max-width: 767px) {
.navbar-default .navbar-nav .open .dropdown-menu {
> li > a {
color: $colDefault;
&:hover, &:focus {
color: $colHighlight; }}
> .active {
> a, > a:hover, > a:focus, {
color: $colHighlight;
background-color: $bgHighlight; }}}
}
And finally, a little gift
I've just made a script which will allow you to generate your theme: TWBSColor - Generate your own Bootstrap navbar
[Update]: TWBSColor now generates SCSS/SASS/Less/CSS code.
[Update]: From now, you can use Less as the default language provided by TWBSColor
[Update]: TWBSColor now supports drop down menus colorization
[Update]: TWBSColor now allows to choose your version (Bootstrap 4 support added)
Updated 2018 for Bootstrap 4
You can create a custom navbar class, and then reference it to change the navbar without impacting other Bootstrap navs..
<nav class="navbar navbar-custom">...</nav>
Bootstrap 4.0.0
I know the original question was for 3.x, but I thought a new Bootstrap 4 example would be helpful too. The CSS required is much less in Bootstrap 4...
.navbar-custom {
background-color: #ff5500;
}
/* change the brand and text color */
.navbar-custom .navbar-brand,
.navbar-custom .navbar-text {
color: rgba(255,255,255,.8);
}
/* change the link color */
.navbar-custom .navbar-nav .nav-link {
color: rgba(255,255,255,.5);
}
/* change the color of active or hovered links */
.navbar-custom .nav-item.active .nav-link,
.navbar-custom .nav-item:hover .nav-link {
color: #ffffff;
}
Bootstrap 4 Custom Navbar Demo 
Bootstrap 3
<nav class="navbar navbar-custom">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">...
</button>
<a class="navbar-brand" href="#">Title</a>
</div>
...
</nav>
.navbar-custom {
background-color:#229922;
color:#ffffff;
border-radius:0;
}
.navbar-custom .navbar-nav > li > a {
color:#fff;
}
.navbar-custom .navbar-nav > .active > a {
color: #ffffff;
background-color:transparent;
}
.navbar-custom .navbar-nav > li > a:hover,
.navbar-custom .navbar-nav > li > a:focus,
.navbar-custom .navbar-nav > .active > a:hover,
.navbar-custom .navbar-nav > .active > a:focus,
.navbar-custom .navbar-nav > .open >a {
text-decoration: none;
background-color: #33aa33;
}
.navbar-custom .navbar-brand {
color:#eeeeee;
}
.navbar-custom .navbar-toggle {
background-color:#eeeeee;
}
.navbar-custom .icon-bar {
background-color:#33aa33;
}
Custom Navbar Demo on Bootply
If the Navbar has dropdowns, add the following to change dropdown color(s):
/* for dropdowns only */
.navbar-custom .navbar-nav .dropdown-menu {
background-color: #33aa33;
}
.navbar-custom .navbar-nav .dropdown-menu>li>a {
color: #fff;
}
.navbar-custom .navbar-nav .dropdown-menu>li>a:hover,.navbar-custom .navbar-nav .dropdown-menu>li>a:focus {
color: #33aa33;
}
Demo with Dropdown
Using Less
You could also consider to compile your own version. Try http://getbootstrap.com/customize/ (which has a apart section for the Navbars settings (Default navbar and Inverted Navbar)) or download your own copy from https://github.com/twbs/bootstrap.
You will find the navbar settings in variables.less . navbar.less is used to compile the navbar (depends on variables.less and mixins.less ).
Copy the 'navbar-default section' and fill in your own color settings. Changing the variables in variables.less will be the easiest way (changing the default or inverse navbar won't be a problem because you have one navbar per page only).
You won't change all settings in most cases:
// Navbar
// -------------------------
// Basics of a navbar
@navbar-height: 50px;
@navbar-margin-bottom: @line-height-computed;
@navbar-default-color: #777;
@navbar-default-bg: #f8f8f8;
@navbar-default-border: darken(@navbar-default-bg, 6.5%);
@navbar-border-radius: @border-radius-base;
@navbar-padding-horizontal: floor(@grid-gutter-width / 2);
@navbar-padding-vertical: ((@navbar-height - @line-height-computed) / 2);
// Navbar links
@navbar-default-link-color: #777;
@navbar-default-link-hover-color: #333;
@navbar-default-link-hover-bg: transparent;
@navbar-default-link-active-color: #555;
@navbar-default-link-active-bg: darken(@navbar-default-bg, 6.5%);
@navbar-default-link-disabled-color: #ccc;
@navbar-default-link-disabled-bg: transparent;
// Navbar brand label
@navbar-default-brand-color: @navbar-default-link-color;
@navbar-default-brand-hover-color: darken(@navbar-default-link-color, 10%);
@navbar-default-brand-hover-bg: transparent;
// Navbar toggle
@navbar-default-toggle-hover-bg: #ddd;
@navbar-default-toggle-icon-bar-bg: #ccc;
@navbar-default-toggle-border-color: #ddd;
You could also try http://twitterbootstrap3navbars.w3masters.nl/. This tool generates CSS code for your custom navbar. Optionally, you could also add gradient colors and borders to the navbar.
